Workhorse Group Incorporated is an American manufacturing company based in Cincinnati, Ohio, currently focused on manufacturing electrically powered delivery and utility vehicles. The company was founded in 1998 by investors who took over the production of General Motors' P30/P32 series stepvan and motorhome chassis.[1] By 2005 they were taken over by Navistar International, which had been selling them diesel engines since before.[2] Navistar then shuttered the plant in 2012, to cut costs after having suffered heavy losses.[1] In March 2015 AMP Electric Vehicles took over Workhorse Custom Chassis, changing the company name to Workhorse Group Incorporated, and began offering a range of electrically powered delivery vans.

As of 2016, the company offers the familiar W62 chassis and a newer, narrow-tracked version called the W88. Their first product was the P-series, based on the Chevrolet/GMC P30-series stepvan/mobile home chassis. An earlier version was the W42 chassis, and they were also managerially involved with the construction of Navistar's eStar electric van, until it too was cancelled in early 2013.[2] Workhorse also briefly offered an integrated chassis/body model called the MetroStar, hearkening back to the long-lived International Harvester Metro Van line.

There were also the low-floor bus chassis (LF72), as well as a rear-engined recreational vehicle chassis called the UFO.

In November 2016, Workhorse announced that they were working on an electrically powered pickup truck, called the W-15. North Carolina's Duke Energy has stated that it will buy 500 of the vehicles, and the city of Orlando is also interested.[3] It is scheduled to have 460 horsepower and a battery range of 80 miles. A gasoline range extender supplies further range.[4]
